I am 14 dpo. Had IUI on 22nd. Tested with an Kroger blue dye and cheap internet. They both looked negative but you know how we do we look at it later on. This is what I see on the blue. I wish the camera picked it up better. In life you dont have to struggle. It's the most convincing evap I've ever seen. If I dont have a period by end of work shift I am going to the store for a first response. Blue dye tests suck.
